Up to four platinum centers can be bound to C 70 , as the synthesis of [C 70 {Pt(PPh 3 ) 2 } 4 ] 1 with idealized C 2v symmetry has shown. The four Pt(PPh 3 ) 2 groups are bound at two types of 6‐6 ring junctions. The stepwise addition of Pt(PPh 3 ) 2 groups occurs initially to the most pyramidalized C‐C bonds at the poles of the fullerene with subsequent additions to the adjacent 6‐6 ring junctions.
